[0038] According to the speaker box 100 of the present invention, the first box 10 and the second box 20 are of a split structure, and the first connecting portion 12 of the first box 10 and the second connecting portion 21 of the second box 20 are welded. Since the structural rigidity of the welding connection is relatively large, the connection strength between the first box 10 and the second box 20 can be met. Compared with the bolted structure of the existing speaker box 100, the loosening of the bolts caused by the vibration of the speaker in the speaker box 100 is avoided, and the stability and reliability are improved. In addition, the first connecting portion 12 and the second connecting portion 21 are both located in the accommodating cavity, which can provide a higher connection force in the middle position of the speaker box 100, further improving the stability and reliability.

In this embodiment, the first body part 121 defines a hollow structure with a first opening, and the first opening is located at one end of the first body part 121 away from the first convex ring part 122. The setting of the hollow structure can reduce a certain weight of the first box body 10, so that the overall speaker box 100 is lightweight, and at the same time, it can also save a certain amount of materials, save costs, and improve the economy of the production of the speaker box 100.

[0040] Specifically, in this embodiment, the support of the first main body portion 121 can extend the length of the first convex ring portion 122 from the second connecting portion 21 along the first direction, thereby facilitating welding of the first convex ring portion 122 and the second connecting portion 21. The first direction is the direction from the first box body 10 to the second box body 20.

[0041] Specifically, in this embodiment, the shape of the first convex ring portion 122 may include but is not limited to a circular ring, an oblong ring, an elliptical ring, a polygonal ring, an irregular ring, and a highway ring.

In this embodiment, the second body part 211 defines a hollow structure with a second opening, and the second opening is located at one end of the second body part 211 away from the second convex ring part 212. The setting of the hollow structure can reduce a certain weight of the first box body 10, so that the overall speaker box 100 is lightweight, and at the same time, it can also save a certain amount of materials, save costs, and improve the economy of the speaker box 100 production.

[0043] Specifically, in this embodiment, the support of the second body portion 211 can extend the length of the second convex ring portion 212 from the first connecting portion 12 along the first direction, thereby facilitating welding of the first convex ring portion 122 and the second convex ring portion 212 .

[0044] Furthermore, in this embodiment, the cooperation between the ring structure of the first convex ring portion 122 and the ring structure of the second convex ring portion 212 can make the welding force between the first box body 10 and the second box body 20 more concentrated, thereby making it easier to achieve a stable welding connection between the first convex ring portion 122 and the second convex ring portion 212.

[0045] Specifically, in this embodiment, if Figure 6 As shown, the length c of the portion of the second protruding ring portion 212 used for welding (ie, the end of the second protruding ring portion 212 away from the second body portion 211 ) along the first direction is greater than or equal to 1 mm.

[0046] Specifically, in this embodiment, if Figure 6 As shown, the length d of the second protruding ring portion 212 along its own radial direction is greater than or equal to 2 mm.

[0047] In some embodiments of the present invention, Figure 5 and 6As shown, a third convex ring portion 123 is provided on one side of the first body portion 121 facing the second body portion 211, and the third convex ring portion 123 is located on the inner periphery of the first convex ring portion 122, and the third convex ring portion 123 and the first convex ring portion 122 are spaced apart. In this embodiment, when the first convex ring portion 122 and the second convex ring portion 212 are welded, the molten adhesive generated by the welding connection will spread along the radial direction of the first convex ring portion 122 or the second convex ring portion 212, and the design of the third convex ring portion 123 can prevent the molten adhesive from spreading to the inside of the third convex ring portion 123, and block the molten adhesive in the interval space between the first convex ring portion 122 and the third convex ring portion 123, so as to prevent the spread of the molten adhesive from interfering with or affecting other parts, thereby improving reliability.

[0048] In some embodiments of the present invention, Figure 5 and 6 As shown, a fourth convex ring portion 124 is provided on one side of the first body portion 121 facing the second body portion 211, and the fourth convex ring portion 124 is located on the outer periphery of the first convex ring portion 122, and the fourth convex ring portion 124 and the first convex ring portion 122 are spaced apart. In this embodiment, when the first convex ring portion 122 and the second convex ring portion 212 are welded, the molten adhesive generated by the welding connection will spread along the radial direction of the first convex ring portion 122 or the second convex ring portion 212, and the design of the fourth convex ring portion 124 can prevent the molten adhesive from spreading to the outside of the fourth convex ring portion 124, and block the molten adhesive in the interval space between the first convex ring portion 122 and the fourth convex ring portion 124, so as to prevent the spread of the molten adhesive from interfering with or affecting other parts, thereby improving reliability.

[0049] Specifically, in this embodiment, if Figure 6 As shown, the distance a1 between the third convex ring portion 123 and the second body portion 211 is 0.3 mm, and the distance a2 between the fourth convex ring portion 124 and the second body portion 211 is 0.3 mm.

[0050] Specifically, in this embodiment, if Figure 6 As shown, a length b1 of the third convex ring portion 123 along the first direction is greater than or equal to 2.3 mm, and a length b2 of the fourth convex ring portion 124 along the first direction is greater than or equal to 2.3 mm.

[0051] Specifically, in this embodiment, if Figure 6 As shown, the minimum spacing distance f1 between the first convex ring portion 122 and the third convex ring portion 123 is greater than or equal to 1.5 mm, and the minimum spacing distance f2 between the first convex ring portion 122 and the fourth convex ring portion 124 is greater than or equal to 1.5 mm.

[0052] Specifically, in this embodiment, if Figure 6 As shown, the length e of the fourth convex ring portion 124 along its own radial direction is greater than or equal to 1 mm.

[0053] In some embodiments of the utility model, the circumferential edge position of the first box body 10 forms a first ring body portion, the circumferential edge position of the second box body 20 forms a second ring body portion, and the first ring body portion and the second ring body portion are welded and connected. In this embodiment, the first box body 10 and the second box body 20 are not limited to the welding connection of the first connecting portion 12 and the second connecting portion 21 respectively located in the accommodating cavity, and the edge position of the circumferential contour of the first box body 10 is also welded and connected with the edge position of the circumferential contour of the second box body 20, which can further improve the connection strength between the first box body 10 and the second box body 20, and improve the connection strength of the overall speaker box body 100.

[0054] Specifically, the welding width between the first ring body portion and the second ring body portion (i.e., the length along the direction of the accommodating cavity toward the outside of the speaker box 100) is smaller than the minimum spacing distance between the first convex ring portion 122 and the third convex ring portion 123, which facilitates the positioning operation between the first box body 10 and the second box body 20.

[0055] In some embodiments of the present invention, Figure 6 As shown, the speaker box 100 is provided with an exhaust hole 30, which passes through the first box 10, the first connecting portion 12, the second connecting portion 21 and the second box 20. In this embodiment, since the first box 10 and the second box 20 are both integrally formed structures, the exhaust hole 30 is provided through the first box 10, the second box 20, the first connecting portion 12 and the second connecting portion 21, thereby avoiding the first box 10 or the second box 20 from being ejected smoothly.

[0056] In some embodiments of the present invention, Figure 3 and 4 As shown, there are a plurality of first connection parts 12, a plurality of second connection parts 21, and each first connection part 12 is welded to a second connection part 21. In this embodiment, a combination structure of a plurality of first connection parts 12 and a plurality of second connection parts 21 and a one-to-one correspondence mode are adopted, which can further improve the higher connection force in the middle position of the speaker box 100, thereby improving the stability and reliability of the overall speaker box 100.

[0057] In some embodiments of the present invention, Figure 2 and 3As shown, the first box body 10 is provided with a through hole 11 connected to the accommodating cavity, and a plurality of first connecting parts 12 are arranged at intervals along the circumference of the through hole 11. In this embodiment, the sound box also includes a speaker, which is arranged in the accommodating cavity and transmits sound through the through hole 11. The plurality of first connecting parts 12 and the plurality of second connecting parts 21 are respectively arranged at intervals at the circumferential positions of the through hole 11, which can focus on improving the connection force of the sound box body 100 near the speaker, thereby avoiding the problem of movement and displacement between the first box body 10 and the second box body 20 caused by the vibration of the speaker, and improving the stability and reliability of the overall sound box body 100.

[0058] Further, in this embodiment, the welding process between the first connection part 12 and the second connection part 21 can be vibration friction welding or hot plate welding. The layout of the first connection part 12 and the second connection part 21 is preferably symmetrical or surrounded by the speaker position close to the speaker box, and can also be arranged according to the shape and structure of the speaker box body 100.

[0059] Furthermore, the welding structure between the first connection part 12 and the second connection part 21 of the speaker box 100 of the utility model can improve the overall strength of the flat speaker box 100. At the same time, welding technology is used between the first connection part 12 and the second connection part 21, and between the first ring body and the second ring body, without adding additional processes or processing time, thereby improving work efficiency.

[0060] The utility model also provides a sound box, which has the above-mentioned sound box body 100.

[0061] According to the speaker box 100 of the speaker of the present invention, the first box body 10 and the second box body 20 are of a split structure, and the first connecting portion 12 of the first box body 10 and the second connecting portion 21 of the second box body 20 are welded. Since the structural rigidity of the welding connection is relatively large, the connection strength between the first box body 10 and the second box body 20 can be met. Compared with the bolted connection structure of the existing speaker box 100, the loosening of the bolts caused by the vibration of the speaker in the speaker box 100 is avoided, and the stability and reliability are improved. In addition, the first connecting portion 12 and the second connecting portion 21 are both located in the accommodating cavity, which can provide a higher connection force in the middle position of the speaker box 100, further improving the stability and reliability.

[0062] The above is only a preferred specific implementation of the utility model, but the protection scope of the utility model is not limited thereto. Any changes or substitutions that can be easily thought of by a person skilled in the art within the technical scope disclosed by the utility model should be included in the protection scope of the utility model. Therefore, the protection scope of the utility model should be based on the protection scope of the claims.
